How to progressive overload12727

Hi guys it's me again, just been wondering bout progression. I read it is one of the most important things to build up muscle and I have a few questions, maybe here's been a thread already but hope u can help me out.
Is it progressive overload necessary in both hypertrophy and strenght training?
How do you guys do this? I heard there are a few variations like pyramid, or adjusting reps per workout till you change weight and all that. thanks for ur answers!

@Thedude67 that is not really what they mean with progressive overload what they mean is that you should progressively ovearload the muscle each time you work it. lets say you are doing a classic bro split so you train every muscle group once a week then you might have chest on monday, this day you manage to get 3 sets of 6reps with 135lb on the benchpress. then the next week you should aim for either
*3 sets of 7reps with 135lb
*4 sets of 6reps with 135lb
*3 sets of 4-5reps with 140lb
And every week you increase something so that you progressively overload force the body to get stronger (adapt) every week

You would be progressively overloading on a weekly basis, but that is an example, not the actual concept

Its pretty simple.
To begin with it helps to have a set desired rep range e.g. 8-12 Then pick a weight that helps you to reach this rep-ran. Each workout you progressively overload the muscle by by playing around with variables, load, sets, etc. When you can perform 12 reps its time to increase weight
